06:18 AM Ruby Feature #22309: Allow super in a module method to work if method was called by refinement method super

@shugo Thank you for the recommendation for implementing this correctly. I used the approach you recommended, and it ended up being much simpler than I expected, even if there were a couple tricky parts. One of those was how to store the... jeremyevans0 (Jeremy Evans)

12:51 AM Ruby Bug #22174: Set operations (&, ^, collect!, flatten, classify, divide) do not preserve compare_by_identity

OK. I submitted https://github.com/ruby/ruby/pull/18848 to fix this in master (same as https://github.com/ruby/ruby/pull/17633 but squashed and with fixed specs). It leaves Ruby 4.0 behavior unspecified. After it is merged, I'll submit ... jeremyevans0 (Jeremy Evans)

05:09 AM Ruby Bug #22174: Set operations (&, ^, collect!, flatten, classify, divide) do not preserve compare_by_identity

From my testing with the example given, Set has returned `false` for all of these operations since `Set#compare_by_identity` was added in Ruby 2.4:

Good point. That does make the stack walking approach unworkable. So I'll work on implementing the lazily created refinement iclass approach in... jeremyevans0 (Jeremy Evans)

Thank you for the review. I think a possible solution to the incorrect behavior in the example you gave would be a ... jeremyevans0 (Jeremy Evans)

08:59 PM Ruby Bug #22273: Aliasing doesn't interact well with Module#prepend

I submitted a pull request to add the initial deprecation warning: https://github.com/ruby/ruby/pull/18807
I think it makes sense to use the same schedule as #22276:
4.1: Verbose-mode deprecation warning
4.2: Non-verbose-mode depr... jeremyevans0 (Jeremy Evans)

03:22 AM Ruby Feature #22309 (Open): Allow super in a module method to work if method was called by refinement method super

Ruby started allowing refinements of modules in 2.4. However, there was one limitation, which is that while the refinement method could call `super` to call the module method, the module method could not call `super`, because it did not ... jeremyevans0 (Jeremy Evans)

03:52 PM Ruby Feature #22266 (Rejected): Stop warning for duplicate keywords in splatted literal hashes

This was submitted in response to #22264, a bug report about parse.y's warnings for splatted literal hashes being different than prism's. As I mentioned, I believe no Ruby programmer would deliberately write a splatted literal hash, so t... jeremyevans0 (Jeremy Evans)

Actually, it doesn't, for the example I gave above:

module M
